Cube of 1373

A cube number is a value obtained by raising a number to the power of 3, or by multiplying the number by itself three times.

When you cube a positive number, the result is always positive. When you cube a negative number, the result is always negative.

This is because a negative number multiplied by itself three times results in a negative number.

The cube of 1373 can be written as \(1373^3\), which is the exponential form.

Or it can also be written in arithmetic form as, 1373 × 1373 × 1373.

In order to check whether a number is a cube number or not, we can use the following three methods, such as multiplication method, a factor formula (\(a^3\)), or by using a calculator.

These three methods will help students to cube the numbers faster and easier without feeling confused or stuck while evaluating the answers.

By Multiplication Method Using a Formula Using a Calculator

The multiplication method is a process in mathematics used to find the product of two numbers or quantities by combining them through repeated addition.

It is a fundamental operation that forms the basis for more complex mathematical concepts.

Step 1: Write down the cube of the given number. \(1373³ = 1373 × 1373 × 1373\)

Step 2: You get 2,586,967,717 as the answer. Hence, the cube of 1373 is 2,586,967,717.

The formula (a+b)3(a + b)^3(a+b)3 is a binomial formula for finding the cube of a number. It expands as:

(a+b)3=a3+3a2b+3ab2+b3(a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3(a+b)3=a3+3a2b+3ab2+b3

Step 1: Split the number 1373 into two parts:
a=1300a = 1300a=1300 and b=73b = 73b=73, so a+b=1373a + b = 1373a+b=1373.

Step 2: Now, apply the formula:

(a+b)3=a3+3a2b+3ab2+b3(a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3(a+b)3=a3+3a2b+3ab2+b3

Step 3: Calculate each term:

a³ = 1300³ = 2,197,000,000
3a²b = 3 × 1300² × 73 = 370,530,000
3ab² = 3 × 1300 × 73² = 20,803,500
b³ = 73³ = 389,017

Step 4: Add all the terms together:

(1300 + 73)³ = 1300³ + 3 × 1300² × 73 + 3 × 1300 × 73² + 73³
= 2,197,000,000 + 370,530,000 + 20,803,500 + 389,017
= 2,586,967,717

So:
1373³ = 2,586,967,717

Step 5:
Hence, the cube of 1373 is 2,586,967,717.

To find the cube of 1373 using a calculator, input the number 1373 and use the cube function (if available) or multiply:
1373 × 1373 × 1373.
This operation calculates the value of 1373³, resulting in 2,586,967,717. It’s a quick way to determine the cube without manual computation.

Steps:

1. Ensure the calculator is functioning properly.

2. Press 1, then 3, 7, and 3.

3. If the calculator has a cube function, press it to calculate 1373³.

4. If there is no cube function, simply multiply 1373 three times manually.

5. The calculator will display 2,586,967,717.

The cube of any even number is always even, while the cube of any odd number is always odd.

The product of two or more perfect cube numbers is always a perfect cube.

A perfect cube can always be expressed as the product of three identical groups of equal prime factors.

• Binomial Formula:An algebraic expression used to expand the powers of a number, written as (a + b)ⁿ, where ‘n’ is a positive integer raised to the base. The formula is used to find the square and cube of a number.

• Cube of a Number:Multiplying a number by itself three times is called the cube of a number.

• Exponential Form:A way of expressing numbers using a base and an exponent (or power), where the exponent value indicates how many times the base is multiplied by itself. For example, 2³ represents 2 × 2 × 2 = 8.

• Volume of a Cube:The space inside a cube calculated as the side length raised to the power of three or cubed.

• Perfect Cube:A number that can be expressed as the cube of an integer.
